MiuzeiPCB Prototype Board Circuit Double Sided Boards Kit for Arduino Kits, 40 Pin 2.54 mm Male to Female Headers Connector, 2P&3P Screw Terminal Block, Semi-Solid Flux, 0.8mm Solder Wire

Great for prototyping.

I have bought this kit 2 times already because it's great for my projects. I work with a lot of electronics and I enjoy doing what I do but, it's kits like this that make it a whole lot easier. It comes with 23 boards for prototypes with a variety of sizes, It has pretty good solder, it is thin too making it easier not to use too much. It has a LOT of pin headers which is perfect because I use them a lot. I had 1 kit for about 2 months now and I still have a lot of pin headers and boards, the solder is not even done halfway. It has screw terminal blocks which is good for securing wires but you still want to use them for other things. The boards are hefty and high quality too, the solder sticks very well to the holes. Overall, I give this 5 stars for quality and ease of use. Will totally buy again!

I like it.

I bought this kit because I've bought off Miuzei in the past and was satisfied. This time was no different!There was a problem with one of the 5x7cm boards. You can see it's not quite right in the picture. In person you can see it's really quite wrong! Miuzei responded right away and was very helpful. I am 100 percent satisfied with their customer service. It was a minor issue and they went above and beyond to make it right!Broken piece asside I would have to say that this is an almost perfect kit! The boards that aren't broken are better than you can resonably expect them to be, even at a higher price. The components are all useful. The only real problem here is the lead free solder. Lead free solder is only good for one thing, being a paper weight. And there are better paper weights out there. This paper weight doesn't even have a rosin core...Everything else works great. Awesome value and fast shipping as always from Miuzei! They are a great company. I really am very impressed with them as always!10/10 would buy again.

The components and paste seem to be pretty good, nothing different from regular electronics sites - HOWEVER - make sure you have your own solder. The solder doesn't melt well with temperatures recommended for electronic components and it smells HORRIBLE.
